Control Erosion

• Areas of open soil can result from a number of different activities—construction, road building, property development, grading adjustments. Unprotected by vegetative cover, soil if prone to erosion from rainfall impact and concentrated surface flow. Used in combination, our techniques offer immediate stabilization and protection to prevent soil and sediment loss. 

• Compost has the ability to absorb a large amount of water for its weight, much like a sponge. When applied as an EarthBlanket™, the compost not only prevents rainfall from directly impacting and loosening soil particles, but also slows flow rates and broadly spreads the flow over the soil surface. Even after the material is saturated, water tends to flow evenly through the EarthBlanket™ rather than concentrating in rills and gullies. 

• Applied directly to the soil  surface, compost prevents soil particles for being moved by water. And, the speed of the water flow is greatly reduced, which reduces the ability of the water to roll and move soil particles. Applied with our hydraulic blower trucks, good contact and adherence between the EarthBlanket™ and the soil is assured so that water cannot flow under the blanket.

• FilterMitts™ or FilterBerms™ intercept downhill flows, slowing the water and detaining sediment behind the device. This allows more water to infiltrate the soil and percolate downward. Water will slowly pass through the stormwater product, and emerge moving more slowly. When used in combination with EarthBlanket™, and installed both at the top and bottom of a slope, water volumes are limited and slowed and move down the slope without eroding the soil.

• In conveyance channels, FilterMitts™ can act as dams which detain excess water, and allow measured flows at reduced speeds. Sediments, chemicals, and nutrients are either held behind the  device, or are adsorbed by the organic material within the structure.
